title: Vesicostomy vs primary ablation for posterior urethral valves: always a difference in outcome?
abstract: OBJECTIVE
  A vesicostomy is believed to have a detrimental effect in boys with posterior urethral valves compared to primary valve ablation. We compared the outcomes of boys managed by initial vesicostomy with those undergoing primary fulguration.
  
  
  METHODS
  The outcomes of 54 boys (23 vesicostomy, 31 primary valve fulguration) over 1 year of age who had not undergone renal transplant were considered. Outcome parameters identified were ultrasound findings, continence status, glomerular filtration rate (GFR) and 1-year creatinine. Dryness was defined as completely dry both day and night with no need to wear pads. Results are presented with 95% confidence intervals.
  
  
  RESULTS
  Ultrasound examinations were normal in 9/19 (47.4%) of the vesicostomy group and 11/24 (45.8%) of the fulguration group. Graded ultrasound results were not significantly different (p=0.24). The vesicostomy patients were more often dry (79% vs 64%, p=0.43). The vesicostomy group had on average higher GFR (95.26 vs 85.79) and lower 1-year creatinine (49.58 vs 52.46) values. After accounting for age differences between groups, there was no significant difference in the GFR and 1-year creatinine values (p=0.16 and p=0.87, respectively).
  
  
  CONCLUSIONS
  There was a tendency for the major outcomes to be more favourable in the vesicostomy group. Although trends were non-significant, confidence intervals were wide and potential differences of clinical importance could not be discounted.
